Procedure

To 3.52 g of 2-[3-(2-cyanoethyl)phenyl]-[1,3]dioxolane was added 60 ml of tetrahydrofuran to dissolve this, and 20 ml of 6 N hydrochloric acid was added. After stirred at room temperature overnight and then concentrated under reduced pressure, ethyl acetate was added, and this was washed successively with an aqueous potassium carbonate solution and an aqueous saturated sodium chloride solution. After dried over anhydrous magnesium sulfate, concentration under reduced pressure afforded 2.68 g of 3-(2-cyanoethyl)benzaldehyde [Compound No. (m)].
